Hydraulic Fracturing Patent Literature on the Rise (With Nanotech Contributions)!

08 September 2012 Cleantech & Nano Publication

Patent filings which refer to hydraulic fracturing are on the rise. In fact, the number appears to have almost doubled in the past five years. This is based on a review of the published patent applications at the USPTO web site. In 2012, pro-rated as of today, there should be about 473 patent applications publishing. In 2007, that number was only 246. From 2008-2010, the number rose to about 355 each year, and then rose dramatically in 2011 to 421.

Nanotechnology continues to be a source of innovation in this and related technologies. See, for example, Abstract below US Patent Publication 2012/0190598 published July 26, 2012 to Pure Liquid Solutions, LLC, on “Metallic Nanoparticle Biocide in Industrial Applications.”

Abstract
A method includes providing and adding a measured dose amount of manufactured metallic nanoparticle material to a carrier material for pre-treatment of the carrier material prior to use of the carrier material and the manufactured metallic nanoparticle material in the sub-surface earth activity. Another method includes accessing a sub-surface earth opening used with a sub-surface earth activity, introducing an amount of manufactured metallic nanoparticle material into the sub-surface earth opening, and treating a sub-surface earth condition present at a sub-surface earth location accessible via the sub-surface earth opening. The sub-surface earth condition is treated with the manufactured metallic nanoparticle material. Another method includes accessing a product from a sub-surface earth location that is extracted in conjunction with the sub-surface earth activity, measuring and introducing a dose amount of manufactured metallic nanoparticle material with the product from the sub-surface earth location.
